Hi. My 3 year old son is now on 4oomg of preventer medication, 6 regular doses of reliever (plus extra) and steroid tablets and is still wheezing and coughing! We are off to see the paediatrician on Friday, but I am interested to know what extra measures people take at home. I am vacuming and mopping every day, damp dusting etc But what else do you do?
